I must admit, the first time you try, it takes hours, sometimes days before you realise what it happening and how to defeat it. However, once you understand how it works, future attempts take minutes.
Obviously once you have worked out how it works, keeping the information to yourself will be beneficial - it'll most likely work with future versions will little or no modification, whereas as soon as you publish your method, there will be a new version of Arma released which defeats that method, and you'll have loads of people PMing you asking you for a new tute (which can get very annoying after a while - pity we can't place filters on incoming PMs)
You have been warned
